| Description: | |
| DMA buffers tend to have a alignment requirement for the | |
| buffers. If this alignment requirement is not met samples might | |
| be dropped from the buffer. | |
| This property reports the alignment requirements in bytes. | |
| This means that the buffer size in bytes needs to be a integer | |
| multiple of the number reported by this file. | |
| The alignment requirements in number of sample sets will depend | |
| on the enabled channels and the bytes per channel. This means | |
| that the alignment requirement in samples sets might change | |
| depending on which and how many channels are enabled. Whereas | |
| the alignment requirement reported in bytes by this property | |
| will remain static and does not depend on which channels are | |
| enabled. |
